Design of learning objects for concept learning: effects of multimedia learning principles and an instructional approach

Literature suggests using multimedia learning principles in the design of instructional material. However, these principles may not be sufficient for the design of learning objects for concept learning in mathematics. This paper reports on an experimental study that investigated the effects of an instructional approach, which includes two teaching techniques – (a) variation theory and (b) representations of subject matter – on the design of learning objects for secondary school algebra concept learning. The results of this study showed that the experimental group performed significantly better than the control group on algebra learning achievement. The results also showed that only the experimental design with the addition of the instructional approach resulted in higher-order mathematical thinking skills and improved procedural skills of the students. Further analysis reveals that concept learning was simplified when multimedia learning principles were applied and the information was presented by the instructional approach.     

Acquisition of procedures: The effects of example elaborations and active learning exercises

This study explored the effects of active learning and types of elaboration on procedure acquisition (writing database queries). Training materials emphasized elaborations of conditions for executing actions versus elaborations of the connection between conditions and actions. In the “active” conditions, participants performed structured exercises designed to encourage active processing. In the “passive” conditions, participants studied examples that contained instructional elaborations. Although excessive instructional information for more knowledgeable learners can hurt performance, our results indicate that condition–action elaborations improved procedural performance the most, in both the active and passive conditions. Active learning required longer training time but was offset by reduced test time.     

Instructional design for distance learning

An intrinsic link exists between instructional design (ID) and distance learning (DL). Their inextricability in the real world raises specific problems of interest in the field of ID. In no other teaching/learning situation is ID so essential as in DL. The conditions of DL make it a necessity to have long-term instructional planning, cost analysis, curriculum and course development, instructional materials development and maintenance, delivery plans, and detailed evaluation rules. Without all of these components, DL simply could not happen. It took some time for this neccessity to be acknowledged, as can be seen in the history of DL. However, ID becomes even more critical as increasingly costly and complex means are used. Conditions of learning have special features in DL, such as the role of media, since the professor, teacher or instructor is replaced by media for either transmitting information or for organizing learning activities. In this paper, the term distance learning will be used to mean media-based, remote or asynchronous learning supported by an instructional system. This paper introduces general features of DL and examines essential aspects of ID for DL, with special emphasis on ID methodologies and on media selection.     

Informed learning design: teaching and learning through engagement with information

ABSTRACT

While higher education teachers are able to use information in sophisticated ways to learn and communicate within their disciplines, they may not be accustomed to teaching their students to use information creatively and reflectively to support their work in a course. This article introduces informed learning design, a curriculum design model by which teachers specifically enable students to learn course content through intentional engagement with information. Drawing from informed learning pedagogy and the variation theory of learning, the design model outlines an instructional pattern for enabling student awareness of critical aspects and features of the object being studied related to both information use and course content.

Networking vs. rote learning strategies in concept acquisition

Following presentation of a slide-tape instructional program, the performance of subjects in two learning strategy groups-networking and rote-was compared to a control group on a concept learning task and a spatial learning task. Networking proved more effective than rote learning and the control group on both tasks; networking also allowed for improved retention over time (in this case, one week). This article reviews some of the research on learning strategies and suggests how the network strategy can enhance learning in academic situations.     

Inserted post-questions and learning from slide-tape presentations: Implications of the mathemagenic hypothesis

Summary From this review it appears that the insertion of factual postquestions into written instructional materials can result in increased learning of both intentional and incidental information. The intentional learning effect is attributed to the reinforcement resulting from review or practice. It is unclear, however, as to whether the incidental learning effect is backward (attributed to review), forward (results in the shaping of mathemagenic behaviors), or motivational. An analysis of intervening variables suggests that postquestions are generally facilitative for mature readers only, result in an increased study time, and are more effective for learners who are not highly motivated. Additional evidence suggests that the effect can be increased by using higher order questions requiring comprehension, application, or analysis. It appears that knowledge of the correct responses to the post-questions will increase intentional learning. No conclusions are drawn concerning the interaction between the use of inserted questions and ability level or passage length.

Application of bayes’ theory in designing computer‐based adaptive instructional strategies 1

Presented are variables and conditions for design of a computer‐based adaptive instructional system. The design strategy uses Bayes’ theory of conditional probability to determine an instructional sequence according to individual student characteristics and needs. The adaptive strategy uses prior estimates based on student pretask and on‐task performance in an algorithm that makes selections of instructional sequence from a table of generated values. The computer system provides a dynamic environment which updates each students on‐task learning progress and modifies the instructional sequence accordingly. The purpose of this adaptive strategy is to improve the effectiveness of the learning environment, resulting in reductions in student learning time while improving task acquisition.     

Simulation-Based Evaluation of Learning Sequences for Instructional Technologies

Instructional technologies critically depend on systematic design and learning hierarchies are a commonly advocated tool for designing instructional sequences. But hierarchies routinely allow numerous sequences and choosing an optimal sequence remains an unsolved problem. This study explores a simulation-based approach to modeling learning hierarchies and the sequencing problem with a special focus on mastery learning over time. Computer simulations of eight hierarchies from the literature address two general questions about hierarchies and sequences: Do different valid instructional sequences for a given hierarchy lead to significant differences in simulated learning outcomes?, and How do hierarchy structures and student ability influence learning? Two findings emerge from the simulations: equally valid instructional sequences can produce widely divergent learning outcomes, and student ability can interact with sequence and hierarchy structure to disadvantage lower-ability learners. The paper concludes with observations on the role of simulations in the analysis and validation of instructional design and large-scale instructional systems.     

Enhancing learning outcomes in computer-based training via self-generated elaboration

The present study investigated the utility of an instructional strategy known as the query method for enhancing learning outcomes in computer-based training. The query method involves an embedded guided, sentence generation task requiring elaboration of key concepts in the training material that encourages learners to ‘stop and think’ about the information already presented before proceeding to new concepts. This study also investigated the effect of varying the level of elaboration (low or high) prompted by the queries. Fifty-one undergraduate students from the general psychology department subject pool at a major university in the southeastern United States received instruction on the basic principles of flight via one of three versions of a computer-based tutorial (no query, low-level elaboration query, or high-level elaboration query). Participants had no prior knowledge or previous experience with the aviation domain. A one-way between-groups design was employed, with the query method serving as the independent variable and a sample size of 17 per condition. Dependent variables included knowledge organization, knowledge acquisition, and instructional efficiency. Overall, results showed that incorporating low-level elaboration queries into the training resulted in improved organization, integration, and application of task-relevant knowledge and higher instructional efficiency. High-level elaboration queries consistently failed to produce significantly better post-training outcomes, possibly due to the increased cognitive load imposed on learners during training. The discussion centers on theoretical and practical implications for promoting and assessing learning outcomes in computer-based training.     

Instructional Guidance and Realism of Manipulatives Influence Preschool Children's Mathematics Learning

Educators often use manipulatives when teaching mathematics because manipulatives are assumed to promote learning. However, research indicates that instructional variables impact the effectiveness of manipulatives. In this article, the authors consider the relations between two instructional characteristics: (a) level of instructional guidance and (b) perceptual qualities of manipulatives. Results from the randomized experiment with preschoolers (N = 72) suggest that learning is improved when instruction is conducted with high levels of instructional guidance and is impacted by the perceptual qualities of manipulatives. Perceptually rich manipulatives decreased learner performance on outcomes associated with conceptual knowledge and improved performance on transfer of learning. In addition, transfer was positively affected by perceptually rich manipulatives when low levels of instructional guidance were present.     

Designing a robot teaching assistant for enhancing and sustaining learning motivation

Although many researchers have pointed out that educational robots can stimulate learners’ learning motivation, the learning motivation will be hardly sustained and rapidly decreased over time if the amusement and interaction merely come from the new technology itself without incorporating instructional strategies. Many researchers have identified that the sustainability of the learning motivation is closely related to the instructional strategies. Accordingly, learners must be well guided by suitable instructional strategies to enhance and sustain their learning motivation. In other words, suitable instructional strategies are required even if introducing educational robots to learners can stimulate learning motivation at the beginning of learning activities. Literature also suggests that systematic instructional strategies can be designed with the use of the Attention, Relevance, Confidence, and Satisfaction (ARCS) model. As the rapid development of robotics, it has become feasible to apply the educational robot for enhancing learning. A robot teaching assistant (RTA) was designed to enhance and sustain learning motivation for the learning of English reading skills. A quasi-experimental design and the Instructional Material Motivational Survey questionnaire were used for data collection and evaluation. The findings showed that the design of the RTA-based learning activities guided by the ARCS model for learning English reading skills can significantly improve learners’ learning motivation, learning performance, and continuance intention.     

Integrating information: A meta-analysis of the spatial contiguity and temporal contiguity effects

This article reviews research on the spatial contiguity and temporal contiguity effects. Research on these instructional design effects has focussed on the instructional benefits for novices of reducing split attention between spatially or temporally disparate but related elements of information. Meta-analytic techniques were applied to 50 independent studies yielding performance data. Major hypotheses regarding the instructional benefits of reducing split attention across time or space were supported, including the effect of a hypothesised moderator, the complexity of learning materials. The analyses indicate that, for complex learning materials in particular, increasing either the spatial or temporal contiguity of related elements of information can lead to substantial learning gains.     

Understanding learner acceptance of learning objects: The roles of learning object characteristics and individual differences

Many organisations and institutions have integrated learning objects into their e-learning systems to make the instructional resources more efficient. Like any other information systems, this trend has made user acceptance of learning objects an increasingly critical issue as a high level of learner satisfaction and acceptance reflects that the users are more willing to continue to use the technology. In this study, an extended version of technology acceptance model (TAM) with two external variables (learning object characteristics and individual differences) was developed to investigate the underlying factors and causal relationships in predicting learners' acceptance of learning objects. This study called for the respondents to progress through two phases of learning object participation: introduction and direct-use experience to investigate the students' perceptions in terms of usefulness and ease of use while utilising learning objects. The findings show that both perceived usefulness and perceived ease of use are determinants of behavioural intention to use learning objects. Learning object characteristics influence both perceived usefulness and perceived ease of use of learning objects; individual differences appear to have no influence upon intention to use learning objects.     

How to use preconceptions? The contact strategy dismantled

The effects of the contact strategy (a computer-assisted instructional strategy aimed at conceptual change in text processing) were investigated by dismantling the strategy. An experiment with 86 Ss (5th/6th-graders) was conducted in which the number of instructional steps was cumulatively varied from 0 steps (no activation) over 1 step (search for old idea) and 3 steps (1. search for old idea; 2. compare and contrast with new information; 3. formulate new idea) to all 5 contact steps (1. search for old idea; 2. compare and contrast with new information; 3. formulate new idea; 4. apply new idea; 5. evaluate new idea). A design with 2 between-subjects factors (instructional strategy and students familiarity with the central concepts from the 7 instructional texts used) and 2 within-subjects factors (type of learning performance test item and time of testing) was used. Dependent variables concerned quality of final conceptions and learning performance. Results indicated that the complete contact strategy was the most effective variant. It seemed to be the case, however, that students mainly focused their attention on the central concepts from the texts. In our view, instructional strategies to foster conceptual change should both support knowledge restructuring processes and offer a solution for this problem of selective attention.     

Implicit sequence learning in dyslexia: a within-sequence comparison of first- and higher-order information

The present study examines implicit sequence learning in adult dyslexics with a focus on comparing sequence transitions with different statistical complexities. Learning of a 12-item deterministic sequence was assessed in 12 dyslexic and 12 non-dyslexic university students. Both groups showed equivalent standard reaction time increments when the sequence was unexpectedly changed, suggesting that learning of the sequence took place. However, a novel analysis comparing transitions of differing complexity within the learning blocks indicated that dyslexic participants were impaired only for higher-order but not first-order sequence learning. No difference was found in the explicit awareness contribution between the two groups and this was found not to correlate with reaction time performance. This result suggests that statistical complexity of the sequence may account for intact and impaired learning performance in dyslexia.     

Exploratory learning with a computer simulation for control theory: Learning processes and instructional support

Computer simulations create a context that is well fitted for exploratory or discovery learning. The aim of the present two studies was to gain deeper insight into what constitutes exploratory learning and to assess the effects of a number of instructional support measures. The domain involved was control theory at the university level. In the first study we made an inventory of exploratory learning processes by observing 17 students working with a computer simulation and analyzing students' thinking-aloud protocols. Subjects received a structured assignment with hints as an instructional support measure. In the second study, 91 students received an open-ended assignment with instructional support that consisted of an information sheet and a set of fill-in forms. On both sheets and forms, six cells were presented. A cell was given for each of the following six learning processes: identifying variables and parameters, generating hypotheses, designing an experiment, predicting, interpreting data, and drawing of conclusions. Information sheets were either of a domain specific or of a general nature. The set of fill-in forms were either free or had the cell HYPOTHESIS already filled in. The statements of the students on the fill-in forms were analyzed in a stepwise order. Twenty-two detailed learning processes were identified and classified. Two of the main classes of processes are transformative and regulative. Both studies showed that students were reluctant to apply learning processes that are considered characteristic for exploratory learning. Furthermore, students had problems with the exploratory learning processes, especially with the processes of generating hypotheses, interpreting data, and drawing conclusions. Effects of the instructional support measures were not conclusive. Hints did not result in significant improvements of the study process. Supporting learning processes with information sheets appeared to help students in performing learning processes, but no different effects of domain specific and general information could be found. Students who were provided with hypotheses showed a higher global activity level and higher scores in domain correctness of their learning processes.     

Analogical instruction within the information processing paradigm: effective means to facilitate learning

Research on the structure of memory has led to evidence that relating unfamiliar information to that which is familiar facilitates the new material's acquisition and retention; moreover, such associations can be efficiently achieved through the use of analogies. The present paper discusses the current information processing conceptualization of memory, the processes of learning by analogy, and the overall desired outcomes of their use to acquire and retain new information. Additionally, instructional implications of how, when, and why to use analogies are discussed.     

Relationships between students' and instructional variables with satisfaction and learning from a Web-based course

The author discusses the results of a study about the effect of students' and instructional variables on satisfaction and achievement in a Web-based course. Results indicated that gender, age, learning styles, time spent on the course, and perceptions of student–student interactions, course activities, and asynchronous Web-based conferences were not related to satisfaction and learning outcomes. Those students who entered the course with better Cumulative Grade Point Average (CGPA) scores achieved higher final grades in the course, but did not express more satisfaction with the learning environment. Computer experience did not influence achievement but experienced computer users were more satisfied with the course. Students who perceived the student–instructor interactions positively felt that their discussion group had performed well during the conferences, and viewed the learning materials used in the conferences positively improved grades and were more satisfied with the course. Students expected instructor-led learning. There is a need to explicitly design an organising strategy to assist students in completing the problem-based learning processes during the Web-based conferences.
